Some may have seen my article, “Using WS2812B Addressable RGB LED Strips with Arduinos“, back in September? As can be seen in that article, controlling Addressable LEDs is pretty straight forward with a basic knowledge of the I2C protocol. I had planned to cobble together interface to allow RGB LED Strip to be Controller by either a LEGO Mindstorms NXT or EV3 Brick, but my teaching commitments and over projects seemed to have forced the idea onto the back-burner. Thanks to Mindsensor, I have no need to warm up the soldering for the idea as they have come up with a ready assembled interface.

In this article, I attempt to describe the LEGO PixyCAM block, which is used in conjunction with the LEGO Mindstorms EV3 Software. Check out the “Getting Started with the LEGO Mindstorms & the PixyCAM” Article for information on how to install the PixyCAM modules (Blocks) into Mindstorms EV3-G Software.

I trust this article will get you up an running quickly with PixyCAM and the LEGO Mindstorms EV3 (NXT). Please make sure you have a LEGO Mindstorms EV3 or NXT brick with a fresh set of batteries. I will endeavor to be as detailed as possible throughout this guide, but it helps if you are somewhat familiar on how to use your LEGO Mindstorms Robotics System.

Good things do sometimes come from disasters. A couple of days ago I was attempting to lift down approximately 5Kg of assorted LEGO parts when the container took advantage of gravity, and headed straight to the floor. This ended in a completely empty storage container, and LEGO dispersed for metres about. Towards the end of the cleanup, I came across a pair of Green Mudgaurds from a LEGO Technics 8291 Green Dirt Bike.

Movable Vertical-Lift-Span Bridges have a movable portion deck which remains horizontal as it is lifted vertically. The amount of headroom available is determined by the variations between water levels and the heights of the lift towers. Water traffic beneath these bridges are usually restricted to low-masted craft, barges and tugs.

BickPi is a system that converts Raspberry Pi into a robot. The project is a board and case that connects LEGO® Mindstorms Sensors, motors, and parts to turn your credit card size computer into a robot. The BrickPi allows you to connect up to 3 NXT Motors and 4 Sensors.

I’ve been working on a very solid, Holonomic Platform to be used with the large 125mm Rotacaster Omniwheels as part of my display for the TAZ-Brick Collector Club’s Brixhibition to be held on the weekend of 20-21 April 2013.

For the forth coming [brixhibition] Exhibition at the end of April, I have been asked to set-up and run a couple of interactive Robot Soccer fields.The Robots needed to be robust and reliable as members of the public will be interacting with them. Also they need to have a a simple, intuitive, and easy to use hand held controller. I have used Sony Playstation PS-2 Controllers, but they have far too many controls that would be unused and confusing to the first time operator. I chose to use a Nintendo Wii® Nun-Chuck Controller for the job.

Want too build awesome robotic contraptions using LEGO Mindstorms NXT motors and sensors and your Arduino Mega? Well now thanks to the boys at Bricktronics, you can with there Bricktronics Megashield Kit.

I have reworked my LEGO Mindstorms NXT Forklift again. This is the Mark IV version of my NXT Forklift with the major difference to previous designs relates to the Boom that moves the Folks Up-and-Down. In this version the Boom is far longer allowing the Forks to be raise 10 Studs from floor level.

Yes it ‘s another Holonomic Platform Robot, but this ones special. I built this Mindstorms Robot to celebrate a package that arrived in the post today from Rotacaster Australia. Yes, more omni-wheels to’ Beta Test’. But these are monsters compared to the original 48mm (2″) Rotacaters.

After seeing this LEGO Mindstorms EV3, Stair Climbing Robot on ‘The NEXT Step Blog‘, I decided to build my own NXT Version. I had attempted a couple before several years ago, but they weren’t overly successful. Now with lots of IMU Sensor add-ons for the Mindstorms NXT, it makes the task a lot easier.

Dexter Industries are currently working a LEGO Mindstorms NXT Interface/ Shield for the Raspberry Pi. The Raspberry Pi is a credit-card sized computer that plugs into your HDTV. Add a mouse and a keyboard and you have a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. It was designed to be used by kids all over the world to learn programming. And the Raspberry Pi will set you back a mere $35.00.

I originally built this LEGO Mindstorms NXT Bug Bot Robot as part of a display at the TAZ-Brick (www.tazbrick.com) Collector Clubs Brixhibition North. The robot proved a hit with the under 10, LEGO Fanatics. Since then I’ve been playing around with the design of my Mindstorms NXT Bug Bot. In this new version I have replaced the 2x RCX type Touch Sensors with 2x NXT type Touch Sensors. The front bumpers had to remodelled to take the NXT Touch Sensors.

This is a LEGO Mindstorms NXT “Bin Emptying Robot Mark III”. It is part of a larger project I have been working on, my “Ball Sorting Factory“. A forklift delivers full Bins of balls to be emptied. The Emptied bins are then taken away to the processing facility to be refilled. The Mark II version worked well, but was a little unreliable, unlike this version. Like the previous version, it uses a “Ball Repository” to store, mix and reload the Production Line with Balls when the “Ball Sorting Factory” needs them.

Isaac Asimov's "Three Laws of Robotics":

A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey orders given it by human beings except where such orders would conflict with the First Law. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
